Abstract: A data processing method for a network adapter includes the network adapter that obtains a first input/output (I/O) command. The first I/O command instructs to store first data in at least one remote server to a local server, and the first I/O command includes address information and length information that are of the data and that are stored in the local server. The network adapter splits the first I/O command based on the address information and the length information to obtain a plurality of I/O read messages. The network adapter sends the I/O read messages to the at least one remote server.

Abstract: A non-volatile memory express (NVMe)-based data read method, apparatus, and system are provided. In various embodiments, a read instruction can be triggered by a host. The read instruction carries indication information of a first address opened by the host to an NVMe controller for addressing and accessing. In those embodiments, the host after obtaining the read instruction can send a data packet to the host. The data packet carries the first address and payload data. Still in those embodiments, the host can, after receiving the data packet, determine a second address based on the first address, and store the payload data into storage space indicated by the second address. The second address may be a private memory address of the host. Because a relationship between the second address and a communication protocol is broken, and the host may access the second address without being restricted by the communication protocol.

Abstract: A data processing method and system, where the method includes: receiving, by a non-volatile memory express (NVMe) controller, a first Peripheral Component Interconnect express (PCIe) packet sent by a host, where a memory in the NVMe controller is provided with at least one input/output (I/O) submission queue, and the first PCIe packet includes entrance information of a target I/O submission queue and at least one submission queue entry (SQE); and storing the at least one SQE in the target I/O submission queue based on the entrance information of the target I/O submission queue. Therefore, an NVMe data processing process is simplified and less time-consuming, and data processing efficiency is improved.

Abstract: A packet data processing method, apparatus, and system. The method is executed by a first processing apparatus, and includes: acquiring packet data that needs to be processed, where the packet data that needs to be processed includes first packet data information and second packet data, and the first packet data information includes a header of the packet data that needs to be processed and a storage address of the packet data that needs to be processed in the first processing apparatus; sending the first packet data information to a second processing apparatus; and receiving first packet data information (includes an updated header after being processed and the storage address) processed by the second processing apparatus, and generating finished packet data using the first packet data information processed by the second processing apparatus and the second packet data.
